. Q :My invention, relates to projecting apparatus for loose or plastic materials, and particu- 7 larlyto a curved tool for insertion into the trajectoryof materialdischarged from the i j maohine'for directing the material into places v normally inaccessible to the projecting machine. The present application is a division a bin onto an endless conveyor moving with sufficient velocity to throw'or project a stream 5 of loose material from the endless conveyor when the direction of movement of the endless conveyor suddenly changes. An example of the use for such a machine is found a in the application of repair material, such as 0 dolomite, to the interior of heated furnaces f j for restoring the surfaces of the fire walls of the furnaces. The machine is carried on a truck and is adapted for rotation about a turn table. Provision is also made for rais "25' ing or lowering the direction ofthe stream of discharged material. Such a machineis shown and described in myco-pending ap- :plication.

' The stream of projected material normally passes through an opening in a furnace wall and-the area accessible to such material is defined. by the size of the opening and the trajectory of the material passing through the opening. Infall such cases however, the inner wallimmediately adjacent the opening is inaccessible to material traversing the opening. Where. it is necessary to repair the inaccessible portions of the furnace wall it i Hhas heretofore been necessary' to permitthe, furnace to cool sufficiently for a workman'to enter the furnace and apply the loose orplastic material. As the value of certain of the materialsincreases when they are applied to a hot surface, itwis' desirable thatthe repair material be applied to thenormally inaccessible portions of the wall at the highest possible temperature of the wall.

' I provide a tool in the form of a spoon in- V sertible through the opening in the wall and into the trajectory of the discharged material.

By'manipulating the spoon it is possible? to deflect the projected material and throw-itl against the inner wall of a furnace or other. structure which is otherwise inaccessible to material projected through an opening inthe wall.

V .BJ'VARNEIH. sonrnrnnon'or LoNnoN, ENGLAND, ASSIGNOR TO BLAW K ox company,

Figure 2 is a perspective view ofa deflecting tool or spoon embodying myinvention,

Referring to Figure 1, a projecting, appa ratus for loose or plast c materials comprises in general a truck 2- on which is mounted a,

motor l tand g'earjtrain 5. for driving the truck, together with aprojecting machine 6 from a bin 9 through a gate 10. The details of the endless conveyor 8; bin 9 and gate 10 are or directing a stream of loose or plastic materials 7 to a desired location. The projecting, machine 6 comprises a emotondriven endless conveyor 8. Material is fed totheconveyor,

except in so far as they are necessaryfor an.

understanding of that invention.

The projecting machine 6 is rotatable'about a turn table comprising a track 11,-by aihandle- 1 2. [The handle 12 comprises a telescoping section 14 connected to the gate 10 for ac tua'ti'ng the latter-by a. turning movement; and a secti0n15 connected by a swivel coupling 16 to the section 14' and extending into the machine ,6 for turning themachine about the track 11, and for raising or lowering thedirection of the stream of the projectedjmaterial, as described in my co-pending applica-. tion. A machine for projecting a' stream of. material is also shown in my Patent No;

1,576,366, dated March 9,1926. V

The stream 7 of projected material is'directed through an opening17 in a wall 18. The wall 18.111213 constituteone of the walls of a furnace wherein it is desired to replenish surfaces of the walls. By adjusting the position of the truck 2 and the angular position of the projecting machine 6 thereon, it is pos-' sible to direct the stream' 7 against a lai'ge part of the furnace walls.
